The Essential Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its event calendar widget. This vulnerability allows authenticated users with contributor-level or higher privileges to inject arbitrary JavaScript code due to inadequate sanitization and escaping of user-supplied input. The injected scripts execute in the context of any user accessing the compromised page, potentially compromising confidentiality, integrity, and availability. The CVSS 3.1 base score is 7.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts to confidentiality, integrity, and availability. No patch or official remediation guidance is currently available from the vendor.

An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages via the event calendar widget. These scripts execute in the browsers of users who visit the infected pages, potentially leading to session hijacking, data theft, or other malicious actions affecting confidentiality, integrity, and availability of the affected WordPress site. The vulnerability is rated high severity with a CVSS score of 7.4. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level permissions to trusted users only and consider disabling or removing the event calendar widget if feasible. Monitor official channels for updates and apply patches promptly once available.
